I have to say the refresh is a nice change of pace. It may not be perfect, but making such a drastic change now gives the writers/artists more license to make more changes down the line. War Machine's look was kind of static, he basically looked exactly the same as when I first started reading comics 20 years ago. I think being able to change the armor will be a good thing in the long run, it will allow the character to grow more. I'm sure it will change again and probably future versions will incorporate old elements. Just look at how many permutations of Tony Stark's armor there have been. Didn't he have cloaking and energy whips at one point?
